What is Amazon FNSKU Explained
When someone starts a new online business, they hear many new Amazon abbreviations and acronyms, such as SKU, EAN, etc. Similarly, one of the most used abbreviations is FNSKU.
What is Amazon FNSKU? What is the work of Amazon FNSKU? Do all sellers need FNSKU?
What is FNSKU?
FNSKU, or Fulfillment Network Stock Keeping Unit, is a unique code assigned to FBA-fulfilled ASINs from Amazon. This unique barcode is used to track inventory in the warehouse and fulfill orders.
When you make an inventory plan to ship products to the warehouse, you need to download the barcode labels from Amazon Seller Central to label each product box.
This barcode is the FNSKU assigned to your product listing. This way, Amazon can keep track of the inventory and ship the right product when you receive the order.
Are ASINs and FNSKUs the same?
Many sellers are confused about FNSKU and ASIN. With this guide, our Amazon SEO experts have tried to explain the difference between ASIN and FNSKU in simple terms. We hope you understand.
An ASIN is a unique 10-digit code automatically generated for each product listed on Amazon, including variations. The FNSKU is used to track and fulfill the product.
ASIN is visible to the customer on the listing page, while FNSKU is visible only to the seller in the seller central dashboard.
UPC Vs FNSKU
UPC (Universal Product Code) and FNSKU use similar mechanisms to track and identify products. The only difference is that FNSKU is Amazon-specific, while UPC is universally used everywhere.
When you are doing FBA (especially retail arbitrage), it is vital to use FNSKU barcodes on the product boxes. This is because many other sellers may be selling the same ASIN product using FBA on Amazon.
So, having a UPC barcode only leads to inventory mixing with other sellers selling the same ASIN. This can be avoided by adding FNSKU labels, as each seller will get a unique FNSKU for every product listing. Adding FNSKU will ensure separate storage in Amazon warehouses.
Is it compulsory to use FNSKU?
No, Amazon does not require you to use FNSKU to label the products. However, as stated above, to ensure the safety of your product inventory, it is recommended that you use Amazon barcodes or FNSKU to label the product boxes.
If you are the only seller selling that ASIN on Amazon, there is no need to worry. You can use manufacturer barcodes (UPC, EAN, etc).
How to create FNSKU in Seller Central?
FNSKU is available for listing created under FBA. Amazon does not create FNSKU for FBM listings.
To check the FNSKU of a FBA listing, go to Manage Inventory and check for “FNSKU” in the columns section. You will see FNSKU assigned in the listing details sections.
